Aggregation-induced emission (AIE) has received great attention. In this paper, Cu²⁺ induced self-assembly and H₂S induced disassembly of two aggregation–induced emission enhancement (AIEE) compounds were reported in this paper. Two salicylaldehyde azine Schiff base were synthesized and characterized. It is found that 1 and 2 are AIEE active molecular both in aqueous solution and crystal state with strong yellow fluorescence. Theirs fluorescence can be selectively quenched in the presence of Cu²⁺ ions with the formation of self-assembly system [1-Cu²⁺]_n. The interaction mechanism has been researched by multiple means. Depending on this reaction, energy changes (ΔG) from 1 to [1-Cu²⁺]_n was also estimated by Scatchard formula. Moreover, the quenching fluorescence was further restored by H₂S both in tube and live cells along with the releasing of AIEE molecular 1. That is, a reversible process between AIEE, self-assembly and disaggregation can be found in the model compound.

聚集引起的排放（AIE）受到了极大的关注。本文报道了Cu ²⁺诱导的自组装和H ₂ S诱导的两种聚集诱导的发射增强（AIEE）化合物的分解。合成并表征了两种水杨醛嗪席夫碱。发现1和2在水溶液和晶体状态下均为AIEE活性分子，具有强黄色荧光。在存在Cu ²⁺离子的情况下，可以通过自组装系统[ 1-Cu ²⁺ ] _n的形成将其荧光选择性淬灭。。已经通过多种方式研究了相互作用机理。取决于该反应，还通过Scatchard公式估计了从1到[ 1-Cu ²⁺ ] _n的能量变化（ΔG）。此外，随着AIEE分子1的释放，在管细胞和活细胞中，H ₂ S进一步恢复了淬灭荧光。也就是说，可以在模型化合物中找到AIEE，自组装和分解之间的可逆过程。
